Does the master camera have its own graphics context to render to? If not then it won't be doing anything other than providing the view and projection matrices that control the slave cameras view and projections matrices. The two slaves cameras are basically independent, all the depth sorting they do is independent. There simply isn't a z sort done w.r.t cameras let alone the master. I don't really what you mean be "two gaussian blobs which fall off to 100% transparent which are overlapped", could you explain. Also could you explain what you are doing with these two slave cameras, do they render to the same graphic context, two separate ones, are they driving monitors, projectors??
